Delegate update: Two more add-ons

— From NBC's Domenico MontanaroAs we enter the heart of state convention season, two more add-on superdelegates selected today. Clinton and Obama have both picked up one each. Clinton got the backing of Maryland add-on, former Lt. Gov. Kathleen Kennedy Townsend, and Obama got the South Carolina add-on, former State Education Superintendent Inez Tenenbaum.

*** UPDATE *** The Obama campaign just announced the support of New Mexico Democratic Party Chairman Brian Colon. That's 2-1 Obama so far today. Numbers adjusted above.

*** UPDATE 2 *** Score another for Obama. The campaign just announced it picked up one of the Maryland add-ons, former Gov. Parris Glendening. That's 3-1 today and expect three more from the Illinois convention as well. Numbers adjusted above.
